HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 261,229, dated July 18 1882.

Application filed March 28, 1881. Renewed April 14, 1882. (ModeL) To all whom it may concern Be it known that I, BENJAMIN B. HILL, of Springfield, in the county of Halnpden and State of Massachusetts, have invented a new and useful Improvement in Self-Inking Hand- Stamps, of which the following is a specification and description.

The object of my invention is to provide a hand-stamp whose die-block is adapted to be provided with two ormore printing-dies, either one of which may be used to make the impression, and be automatically inked therefor at each successive downward and upward movement of the hand-piece in the ordinary operation of printing with the stamp; and I accomstamp'having my invention applied. Fig. II

is an end view of the same. Fig. III is a vertical transverse section of the stamp through the inking-bed and parts below on the line D of Fig.1. Fig. IV is a vertical longitudinal 2 section of the die-block and its rotating yoke.

Fig. V is a-plan view of the die-block and its yoke, and the pivot upon which it revolves. Fi'g. VI is an end view of the die-block and its yoke. Fig. VII is a transverse section through 0 the die-block yoke, showing the latter and the die-block in a partially reversed position in the operation of printing; and Fig. VIII is a longitudinal vertical section of the end of the die-block yoke, showing the spring-catch 3 5 which retains the die-block in the position into which it may be placed for printing.

In the drawings, A denotes the stationary frame of an ordinary self-inking hand-stamp; O, the tube containing the actuating-spring; 1,

40 the movable frame, with the hand-piece secured to its upper portion, and ordinarily a dieplate pivoted in the lower end of the movable frame. Instead, however of the ordinary dieplate used, I pivot what might more properly be termed a die-block, as 10, in the lower end of the movable frame, having any desired number of sides, each adapted to have a die secured thereto or made thereon.

In the drawings a die-block having three sides is shown, which is provided with a jonrnal-bearing, as 11, at each end, preferably equidistant from the sides of the block, and which journal-bearing may be continuous, eX- tendingthe entire length ofthe block, as shown in Fig. 1V, and the ends of this pivot or journal may be grooved to receive a spring-ring at each end after being inserted into place.

The yoke 7 is pivoted upon the journal, or is attached thereto at one end, and extends around the block 10 to its other end, and is there pivoted or attached to that end of the journal; and this yoke is provided with a longitudinal slot, as 5, at one end, and at the other is provided with a spring catch or de' tent, as 8, whose end projects inward toward the die-block and engages with any one of a series of indents, as 9, made in the end of said die-block, the number of said indents being equal to the number of sides of the block having dies attached.

One end of the stationary frame A is provided with a vertical slot, as 3, and a bar, as 2, is pivoted midway its length to the inside of said frame by the side of this slot, with a pin, 6, projecting inward from the lower portion of said bar and into the slot 5 in the yoke 7.

The lower ends of the movable frame 1 are pivoted to the journals ll of the die-block, and a pin, as 4, projects inward from the upper portion of the movable frame 1, which, when the said frame is moved down, passes down in the slot 3 in the stationary frame A and against the inner curved edge of the vibrating bar 2. As the movable or actuating frame 1 moves down the journal 11 at one end of the die-block first strikes against the inner edge of the lower part of the vibrating bar 2, moving the lower end of the latter outward, and as the pin in the lower end of the vibrating bar projects into the slot 5 in the yoke 7 ata point quite near to the journal 11 the main part of the yoke is moved to one side or partially revolved upon the journals 11, partially revolving the die-block also, which is held fast to the yoke. The die-block being thus revolved somewhat more than one-fourth of a revolution, as the actuating-frame 1 is moved farther down the pin 4 in the upper part of said frame strikes against the curved inner edge of the upper end of the vibrating bar 2, moving its upper end outward and its lower end and projectin g pin inward, and causing the yoke and the die-block held fast by the detent 8 to complete a half-revolution upon the journals 11, when the die-block will be in a reversed position from that which it occupied when the actuating-frame was in its most elevated position, and the die will in this lower and reversed position make an impression upon any material placed beneath to receive it. In the upward movement of the actuating-framel the journal 11 at the end of the die-block first strikes against the inner curved edge of the lower end of the vibrating bar, and moving its projecting pin and the yoke to one side, and causing the latter and the die-block to make a partial revolution back again on the journals 11, and as the frame andjournals 11 move upward one end of the latter strikes against the inner curved edge of the vibrating bar at its upper end and throws it outward and its lower end and its projecting pin inward, causing the dieblock to complete its half-revolution backward, and resuming its original position before it was moved down. When in this elevated position the same die which made the impression at the last downward movement of the frame 1 will be held by the frame up against the inkingpad located and exposed in the lower side of the part B of the stationary frame A, and will thereby receive the ink necessary-for making the next impression at the next downward movement of the hand-piece and actuatingframe 1. Any one of the dies of the three on the three-faced die-block 10 may thus be used for making successive impressions; and if any one of the dies is being used and it is desired to use one of the others, the block 10 may be revolved upon the journals 11, springing the detent 8 out of its recess, and when the desired die is exposed for use, or in a position opposite theyoke 7, the detentS will then spring into the appropriate recess, as 9, and the die-block be held in the same position until it is again turned with the fingers to expose the desired die.

In the illustration a die-block is shown having three faces, to each of which adie may be secured different in its character or printingmatter from either of the others; but it is obvious that a die-block having any desired number of faces may be used, each having a die different in character or matter from the others, which is oftentimes a matter of no. little convenience.

I am aware that stamps having die-blocks with two sides, each provided with aprintingdie, have heretofore been used, in which the die-block was caused to make an intermittent rotary movement always in the same direction by the successive downward movement of the hand-piece and movable frame, in which case with a die-block having two faces or sides and two dies the same die could be made to print only at each alternate downward movement of the hand-piece and movable frame. In my invention the downward movement of the frame I reverses the die-block, causing any particular and desired die to make the impression, and the next upward movement of the said frame reverses the die-block back again, the latter making but half a revolution at each downward movement of the frame 1 and a halfmovement of said frame.

It is evident that the desired number of de-' tents may be made in the end of the die-block and arranged to engage in an indent made in the inside of the yoke 7, if desired; but I prefer the construction hereinbefore described.

If it is desired to have more than one dieblock, the journal may be disengaged from its bearings in the lower end of the frame 1, the die-block thereon removed from the journal and another slipped onto the journal, and the latter again secured in its bearings in the frame, all with very little trouble. In this mannera great variety of printing may be done with one stamp by having the desired variety of die-blocks, one being removed and another being substituted when desired.

One or moreof the faces of the die-block may have a recess, as 15, therein, in which to insert type to be used for dating purposes in connection with thepermanent die made thereon or secured thereto.

Having thus described my invention, what I claim as new is-- In a hand-stamp, the combination of a fixed frame provided with an inking-pad exposed on its lower side, an actuating-frame, a revolving die-block having a number of sides, as described, and pivoted upon journals having a bearing in said actuating-frame, an oscillating yoke loosely embracing the ends of said dieblock, and a spring-detent or catch mechanism between said yoke and die'bloek, so that the latter may be revolved in the yoke to bring and retain either of its printing-dies into position to be used for printing and for having the ink automatically applied for printing by the movement of the actuating-frame in the operation of printing, substantially as described.
